  • Weather and Pests
    Volume 52 Number 18 August 10, 2007 Weather and Pests Widespread rainfall this week brought variable levels of moisture to the state. Portions of the southern agricultural areas received generous amounts of precipitation, and this has improved the prospects for late-planted sweet corn, soybeans and alfalfa regrowth. High temperatures and humidity favored an increase in some diseases that were relatively inactive during the prolonged period of dry weather. Crops in the central and northern areas remain under severe drought stress. Corn growers from the east central area report poor grain fill and attribute it to the continued dry conditions. Second and third crop hay cuttings are short and yields are generally below normal. Corn rootworm beetles are now very active and being encountered in high numbers in several counties.

  • Preserving a Critical Fishery Resource in Inle Lake, Myanmar for Sustainable Fisheries and Food Security
    Preserving a Critical Fishery Resource in Inle Lake, Myanmar for Sustainable Fisheries and Food Security Myo Min Hlaing Inle carp (Cyprinus intha) is a bottom dweller species of carps which is endemic in Lake Inle of Myanmar. This species of carp is being driven to near extinction due to overfishing and environmental degradation of its natural habitat. Lake Inle is the second largest natural inland water body in Myanmar. Situated in Shan State in the northeastern part of the country, Lake Inle has an area of about 116 km2 and sits in a tropical monsoonal area with diverse species of flora and fauna. Recently, the Lake has suffered environmental degradation due to deforestation and agro-chemical pollution, a situation that affects not only the Inle carp that inhabits the Lake due to its degrading water quality but also the Intha fishers who depend on Lake Inle and Inle carp fisheries for their livelihoods. Inle carp (Cyprinus intha) is a Cyprinid fish commonly found in Lake Inle and an endemic species in Myanmar. In 2011, the IUCN Red List declared the Inle carp as endangered as it had been impacted by the introduction of some Cyprinus species in the Lake. C. intha inhabits the shallow zone of the Lake, especially in areas with dense submerged vegetation and muddy with high organic bottom. Spawning of this species usually takes place in waters with temperature ranging from 24°C to 26°C, between November and March. The inland waters of Myanmar include natural inland and seasonal water bodies as well as freshwater fishponds that Clockwise: Map of Myanmar are being tapped for fisheries, which has been playing a showing Lake Inle, and intha fishers’ technique of rowing boats in Lake Inle with a unique motion vital role in the cultural and socio-economic advancement that has become a symbol of the local intha tribe of the country.

  • Morphology and Biology of Lac Insect and Different Strain
    LECTURE 11: MORPHOLOGY AND BIOLOGY OF LAC INSECT AND DIFFERENT STRAIN. 1. Degree Programme: B. Sc (Ag) 2. Year: 3rd 3. Semester: VI 4. Course Name: Management of Beneficial Insects 5. Course Code: AEZ-302 6. Topic Name: Morphology and biology of lac insect and different strain. 7. Date: 27.03.2020 8. Course Instructor: Mr. G. S. Giri, Dr. Neeraj Kumar, Dr. R. Prasad INTRODUCTION The word lac is derived from the sanskrit word laksha, which represents the number 100,000. Lac is the harden secretion or outer protective covering of lac insect. The insect produce three products namely resin, dye and wax of great commercial importance. The resin commonly called lac and is the only product of animal origin. It is commercially available in the market as shellac or seedlac or button lac. TAXONOMY Lac insect : Laccifera lacca Order : Hemiptera Sub order : Homoptera Super family : Coccoidae Family : Kerridae Genus : Laccifera Species : lacca DISTRIBUTION India, Pakisthan, Sri Lanka, Myamar, Malaysia, China, Thialand MORPHOLOGY Lac insect is a hemimetabolous i.e. it undergoes gradual metamorphosis. It has three life stage namely egg, young one and adult. The young ones are called as nymph. The nymphs are similar to adult in all aspects except their size and reproductive organs. The adult male and female are different from each other. Female is about three time larger than the male. Male: These are pinkish red in colour and may be winged or wing less. Winged male possesses only one pair of translucent membranous forewing. They are mostly found during dry season (Baisakhi and Jethwai).

  • Wax, Wings, and Swarms: Insects and Their Products As Art Media
    Wax, Wings, and Swarms: Insects and their Products as Art Media Barrett Anthony Klein Pupating Lab Biology Department, University of Wisconsin—La Crosse, La Crosse, WI 54601 email: [email protected] When citing this paper, please use the following: Klein BA. Submitted. Wax, Wings, and Swarms: Insects and their Products as Art Media. Annu. Rev. Entom. DOI: 10.1146/annurev-ento-020821-060803 Keywords art, cochineal, cultural entomology, ethnoentomology, insect media art, silk 1 Abstract Every facet of human culture is in some way affected by our abundant, diverse insect neighbors. Our relationship with insects has been on display throughout the history of art, sometimes explicitly, but frequently in inconspicuous ways. This is because artists can depict insects overtly, but they can also allude to insects conceptually, or use insect products in a purely utilitarian manner. Insects themselves can serve as art media, and artists have explored or exploited insects for their products (silk, wax, honey, propolis, carmine, shellac, nest paper), body parts (e.g., wings), and whole bodies (dead, alive, individually, or as collectives). This review surveys insects and their products used as media in the visual arts, and considers the untapped potential for artistic exploration of media derived from insects. The history, value, and ethics of “insect media art” are topics relevant at a time when the natural world is at unprecedented risk. INTRODUCTION The value of studying cultural entomology and insect art No review of human culture would be complete without art, and no review of art would be complete without the inclusion of insects. Cultural entomology, a field of study formalized in 1980 (43), and ambitiously reviewed 35 years ago by Charles Hogue (44), clearly illustrates that artists have an inordinate fondness for insects.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. There has been growing interest in the dyeing of textiles with natural dyes. The research about the adsorption properties of natural dyes can help to understand their adsorption mechanism and to control their dyeing process. This study is concerned with the kinetics and isotherms of adsorption of lac dyes on wool, silk, and nylon fibers. It was found that the adsorption kinetics of lac dyes on the three fibers followed the pseudosecond-order kinetic model, and the adsorption rate of lac dyes was the fastest for silk and the slowest for wool. The activation energies for the adsorptionprocessonwool,silk,andnylonwerefoundtobe107.15,87.85, and 45.31 kJ/mol, respectively. The adsorption of lac dyes on the three fibers followed the Langmuir mechanism, indicating that the electrostaticinteractionsbetweenlacdyesandthosefibersoccurred.Thesaturationvaluesforlacadsorptiononthethreefibers decreased in the order of wool > silk > nylon; the Langmuir affinity constant of lac adsorption on nylon was much higher than those on wool and silk.

  • Decco Communication on Shellac Resin
    Decco Communication on Shellac Resin 1 BACKGROUND Some supermarkets in Australia have inquired about the quality of shellac resin used as an ingredient in apple wax coatings. Apple packers, who are EE Muir’s customers, have in turn asked EE Muir to provide documentation on the quality of shellac and manufacturing practices used by Decco. Below are a number of documents and explanations that Decco is providing to EE Muir in support of Decco’s quality and manufacturing practices. 2 WHAT IS NATURAL SHELLAC RESIN Shellac is a natural gum resin secreted by the lac beetle (laccifer lacca) which lives on trees in tropical and subtropical regions. The natural gum resin is harvested from the trees and then processed and refined into flakes and powders of pure natural shellac resin. 3 SHELLAC AND ITS USES Natural shellac resin has unique properties and is used in various applications such as: Fruit coatings, Confectionery (Candy & Chocolates coating), Pharmaceutical (Tablets coatings) as well as several non- food segments. Shellac is used as a 'wax' coating on citrus fruit to prolong its shelf/storage life. It is also used to replace the natural wax of the apple, which is removed during the cleaning & washing process. In these applications, the wax coating prevents moisture loss (shrinking, shriveling of the fruit) and preserves the textural and eating quality of the fruit. When used for this purpose, it has the food additive E number E904 which is recognized and adopted worldwide. Shellac is also used as a glazing agent on pills, food, chocolate & candies, in the form of pharmaceutical glaze or, confectioner's glaze.

The study of environmental resources usually gets meagre attention particularly in developing countries. This is the first-attempt to study population dynamics and fishery management parameters of a very important aquatic environmental resource Cirrhinus mrigala (Mrigal carp) in Pakistan. For this, six monthly surveys, January to June 2020, collected 720 samples numbers (n), ranging (R) in size from 14 to 37 centimeters (cm) (22±5.445) and weighing from 30 to 527 grams (g) (148±110.673). Collected data was statistically analysed by FAO-ICLARM Stock Assessment Tools II (FiSAT-II). Length-weight relationship (LWR) for Mrigal carp was measured as W=0.014 L2.936 having goodness of fit (R2) value of 0.987. -1 Computed values of asymptotic length (L∞) and growth coefficient (K) were 38.85 cm and 0.180 years . Other fishery parameters, viz., theoretical age at which length is zero (to), growth performance index (GPI), total mortality (Z), natural mortality (M) and fishing mortality (F) were estimated at -0.056, Φ'= 2.434 year, Φ= 1.130 year, 1.170 years-1, 0.493 years-1 and 0.677 years-1, correspondingly.

The strongest antifeedants for L. decemlineata larvae and adults were linalool-derived unsaturated lactones (Z) 5-(1.5-Dimethyl-hex-4-enyldiene)-dihydro-furan-2-one and (E) 5-(1.5-Dimethyl-hex-4-enyldiene)-dihydro-furan-2-one, and for cpB larvae – saturated lactone with three alkyl substituents, the 4-isobutyl-5-isopropyl-5-methyl-dihydro-furan-2-one. the settling of M. persicae on plants was strongly deterred by iodolactones: 5-(1-iodo-ethyl)-4.4-dimethyl-dihydro-furan-2-one, 5- iodo-4.4.6-trimethyl-tetrahydro-pyran-2-one, 5-iodomethyl-4-isobutyl-5-isopropyl-dihydro-furan-2-one, and the saturated lactones: 4.4.6-Trimethyl-tetrahydro-pyran-2-one and 4-Isobutyl-5-isopropyl-5-methyl- dihydro-furan-2-one.
